// 定义音频源和目标文件路径
String sourceFilePath = "/data/record.amr";
String destinationFilePath = "/data/record.mp3";

// 创建音频解码器
AudioDecoder audioDecoder = AudioDecoder.createAudioDecoder();

// 设置音频源
Source source = new Source(sourceFilePath);
audioDecoder.setSource(source);

// 创建音频编码器
AudioEncoder audioEncoder = AudioEncoder.createAudioEncoder();

// 设置音频编码器的目标文件路径和格式
Format format = new Format();
format.setMimeType("audio/mp3");
format.setAudioFormat(new AudioDataFormat());

audioEncoder.setOutputFile(destinationFilePath, format);

// 创建音频转换器
AudioTransform audioTransform = AudioTransform.createAudioTransform();

// 设置音频解码器和编码器
audioTransform.setDecoder(audioDecoder);
audioTransform.setEncoder(audioEncoder);

// 开始转换
audioTransform.transcode();

// 释放资源
audioDecoder.release();
audioEncoder.release();
audioTransform.release();
